For the design, we need the required flow rate and the pressure drop to be overcome. We also need information on the fluid being pumped, its temperature and density, as well as the operating duration and control range. Also important are installation dimensions, connection geometry, flow path, noise specifications, and the electrical supply. If there are any special protection requirements, these must also be taken into account from the outset. Based on this information, we coordinate the fan, motor, housing, and necessary accessories.

A duct fan is integrated into a duct or air duct run. A wall-mounted fan is suitable for installation in a wall, opening, or enclosure. When selecting a fan, we consider not only the available installation space but also the airflow pattern, connection options, mounting, and access for maintenance. The appropriate design is therefore determined by the specific installation situation and the required operating point.

Unfavorable inflow or outflow conditions, tight bends, and nearby fixtures can affect the actual airflow capacity, noise level, and vibration behavior. That is why we consider not only the fan itself but also how it is integrated into the air duct system. During the design phase, we take into account the available space, connection points, and flow conditions to ensure that the fan and its installation environment are well-suited to one another.

Re-engineering is an option when an existing fan or key components are no longer available, drawings are missing, or operating requirements have changed. We document the existing geometry, the mechanical and electrical interfaces, as well as the current and future operating points. We then determine which components can be reused and which need to be redesigned. This results in a solution tailored to the existing system.

The motor, control system, and accessories must be suitable for the operating point and the conditions at the installation site. Among other factors, we take into account power, voltage, frequency, the desired speed control, temperature, and, if applicable, special protection requirements. Depending on the application, components such as frequency converters, vibration monitoring, temperature monitoring, sound attenuation, or vibration isolators may be appropriate. The specific components required are determined on a project-by-project basis.
